Ever since the paths of these two mighty warriors (well... Chakaal at least is a mighty warrior) crossed in the tale commonly known as "Chakaal", Chakaal has done her best to avoid running into Groo.
Groo on the other hand, is still waiting for Chakaal to accept his, about a dozen, marriage proposals. The most promissing reply he's gotten so far is: "I would rather be trampled to death by rabid Elephants!"
Chakaal was last seen in the Kingdom of King Senil. Because of Groo and an youth potion, she ended up in the shape of a little girl. Hopefully she's back to her normal, good looking, shape by now :-)
