From publisher blurb:
Visit Ironskull Castle, the headquarters of Lady Raelle Ironskull, mercenary warlord turned magical arms dealer, mistress of Eldritch Arms. Potential adventure seeds:
Intervene in factional negotiations for weapons and magical devices
Mission-Impossible-style invasion and theft of exotic magic items
Is Lady Ironskull really planning to march forth with an undead army at her back? Stop her (or join her!)
An entire castle filled with nasty surprises, strange magic items, and detailed NPCs. Trouble never stops coming out of Ironskull Castle, and Lady Raelle can also be used as a long-term “Evil Overlord” that can spawn multiple follow-ups. By the way: She’s read the Evil Overlord manual.
The last page of the adventure contains 42 print-them-yourself tokens for monsters and NPCs that appear in the adventure (in black-and-white).
