The Rolf quest is a complex quest to find the legendary dwarf Rolf, and to carry out his bidding. It requires assembling a map to find Rolf, and killing his nemesis. The PC must avoid killing any living dwarves, apart from dwarven chaos knights, prior to meeting Rolf. Depending on how the quest is resolved, it can lead to volcanoes appearing in the Drakalor chain.
There are 6 antediluvian dwarven map fragments scattered across the chain. Reading one when the PC possesses all 6 fragments allows the PC to combine them into a map to Rolf's fortress.
The location of this fragment is revealed by talking to the drunken dwarf NPC in Lawenilothehl several times. He will eventually require you to guess the ID level this fragment is located on; the level number is an anagram of the drunken dwarf's name. Once this riddle is successfully answered, a map fragment can be found on the specified ID level. This map fragment is generated on a trap, but it will automatically jump into the PC's pack upon leaving its ID level. Attacking Hotzenplotz will anger the drunken dwarf, rendering this map fragment impossible to find if the PC has not already answered the riddle (drunken dwarf can revert to peaceful state; panic induced by companion attack worked).
Ancient shop fragment
A map fragment can be found in a scroll shop in the Antediluvian dungeon. This fragment will often be sold for an exorbitant price.
A map fragment can be found by digging up Griff's remains.
The dwarven gladiator NPC in the arena will give the PC a map fragment if they chat with him while wielding Rolf's Saviour and Rolf's Companion. Rolf's Savior can be guaranteed by talking with Thrundarr about "Rolf" before receiving his 4th quest reward while lawful. The gladiator will not give the fragment to orcs and trolls, however. He will drop the map fragment when he dies, but killing him forfeits the chance of entering Rolf's throne room, as the gladiator counts as a dwarf. So trolls and orcs will need a strong companion to kill the gladiator for them, or beat his health down and let the companion finish him off.
First, talk with Thrundarr about "Rolf". Then, talk with the grizzled dwarven veteran NPC in the HMV. This will allow the PC to find an eerily silent glade to the north of the mad minstrel's hut. An ancient dwarven key can be found by digging up the white grave there. This key can then be used to unlock the portal at the bottom of the sinister dungeon. The portal leads to a four level dungeon, which features antediluvian enemies. The second and third levels are shifting dungeons, and the map fragment can be found lying on a trap on the forth level.
One map fragment can be dropped by a random monster.
Once the PC reads the antediluvian dwarven map, Rolf's fortress can be found in the mountains directly east of Terinyo. Rolf's fortress consists of four levels, with Rolf at the bottom.
The first level of the fortress has a moat populated by random aquatic monsters. The first proper room contains four pools. To the north is a peaceful dwarven guardian spirit and piles of bones. To the south is a room full of dwarven ghost warriors who become hostile upon noticing the PC. The dungeon continues east through a gauntlet of respawning constructs. Most actions taken on the level (e.g. picking up items, using items, breaking walls and doors) will cause angry stone golems and stone statues to spawn from here. The final chamber to the east has two secret doors. The secret door to the east leads to the artifact unpick axe, guarded by a truesilver golem. The secret door to the south leads to the rest of the fortress levels.
Teleportation is not allowed on this level, although most of the walls are diggable, with the exception of those around the secret doors.
The second level of the fortress is a dungeon level with a normal random layout. It features antediluvian enemies. Teleportation is allowed on this level.
The third level of the fortress has a large, open layout featuring many monsters. Most of the monsters are initially peaceful, but will become hostile when the PC ascends from the final level. A room full of antediluvian alcohol is hidden behind a secret door in the northeast of the level. A pool and the stairs down are on the west side of the level. Teleportation is not allowed on this level. If the PC has killed ANY living dwarven monster types (e.g., Kherab) apart from dwarven chaos knights, they will not be allowed to descend to the final level.
The final level of the fortress is a single, huge room. There are six pools on the east end, and Rolf is initially found on the west end. Teleportation is not allowed on this level.
Rolf will assign you a quest if you chat with him after giving him his axe and shield. Rolf will attack non-lawful Dark Elves, Orcs, and Trolls when chatted with. Rolf will attack chaos knights when chatted with, regardless of alignment. Rolf asks you to slay the stone dragon king and return with its heart. After receiving this quest, the stone dragon caves can be found in the mountains to the west of the pyramid.
Stone dragon caves
The stone dragon caves consist of five levels in total. All levels have a reduced line of sight (similar to the water dragon cave), allow digging and teleportation, and are subject to earthquakes at random intervals. The caves are populated by all types of earth and stone monsters, as well as baby stone dragons, stone dragons, ancient stone dragons, and great stone wyrms. The first four levels have cavernous layouts, while the final level has a special layout that includes the stone dragon king's treasure hoard. The stone dragon king drops the stone heart when killed.
Turning in the heart
Giving Rolf the stone heart completes his quest, and he rewards the PC with the Gleaming dwarven rune axe and Gleaming dwarven shield, as well as +2 Strength, +6 Toughness, and +6 Willpower. Alternatively, the heart can be corrupted prior to returning it. This forfeits the rewards from Rolf, but opens up another quest line.
The stone heart can be corrupted by using it while the PC possesses the Chaos Orb of Elemental Fire. Doing this gradually causes mountains to turn into volcanoes, and other terrain to become more mountainous.
Entering any volcano on the wilderness map places the PC in the same volcano dungeon. Leaving this dungeon places the PC on a random volcano on the wilderness map. This can eventually be used to visit any closed off area on the wilderness map, including the sinister library, although it may take a very long time for volcanoes to spawn in the necessary places. The volcano itself is a 16 level cavernous dungeon with lots of magma and a very high rate of special dungeon features. The heart of Ancardia, an artifact amulet, is found on the ground on the 16th level. Visiting the volcano is not required to complete this quest line, but it will become inaccessible upon its conclusion.
Stopping the cataclysm
Yggaz the fool can be tamed by giving him some antediluvian alcohol. Leading him all the way to the ice queen will cause them to reunite, which stops the generation of further volcanoes and renders existing volcanoes dormant. At this point, it will no longer be possible to visit the volcano or to complete any remaining ice queen quests.
