Wheloon Prison has been on the brink of collapse ever since a strange magical manifestation appeared around Oldstone Hall. The Cormyrean authorities are looking for a brave adventurer willing to take on Prison's Problems.
Heroic version (level 16) bestowed by Davny Selkin, Epic version (level 26) bestowed by Edric Crastmere, both in the northwest section of Eveningstar or the northwest section of Wheloon Docks (near the ramp up to Wheloon Prison). The quest givers are all in the Wheloon Docks, near the chain givers.
Upon completing all the above quests, the original chain giver NPC offers you a list of named items that are chest drops within the arc. Plus, the list sometimes includes a random item with the Wondrous Craftsmanship property on it. This can be a new kind of item, a "Compass" which equips to the Trinket slot. The item is typically, but not always, for a jewelry or clothing slot.
Named items are all Normal version, and both named items and random Jewelry/Clothing are BtCoE.
Also received a choice of 4 ML 1 lootgen items after running Friends, Lesson, and Hunt (the first three in order) on Heroic.
