“ After a long night of reveling and merriment celebrating their latest victory, one of the PCs awakens with his/her head shaved and a large ornate tattoo on top of their head. Tacky, yes but also a painstaking work of art that has left them with a headache to beat their hangover. The kicker? It is a huge symbol of the god of Evil, Assassins, the Drow, Munchkins, something really really offensive”
“ The PCs discover a large white ball in the branches of a tree, or in a niche in a cave. Unless magically examined, or by a PC with a specialty in insects, it is a plain, smooth white ball. After a short time, it hatches and releases hundreds of spiders, cockroaches, some other nasty bug”

The party's presence will be 'requested' for this expedition.”
