Ultima VI: The False Prophet/Side quests

The best time to complete the side quests is after all the eight shrines are cleared and before start the subsequent quests, so that the characters can gain experience and level up praying at the shrines.

Quests:
 * The library of the Lycaeum
 * Dungeon Despise and the Heroes' Hole (connected dungeons)
 * Dungeon Deceit
 * Swamp Cave
 * Cyclops Cave
 * Spider Cave
