Something to be brave at... Thanatos was also ready to do nothing. However, his fingers brush against something in his pocket. Well, it's not the bravest thing, but maybe he can give this with some amount of confidence. Thanatos hasn't had a good track record when it comes to giving people keepsakes.

So, he tries before he has a chance to overthink it and muddle through his words.

"Here. This is the Darkness Pull." Thanatos holds out a small string with a dark crystal affixed to the end. It's about a finger's length and just as wide at the crystal, easy to conceal and carry around. The keepsake could be attached to a zipper to look like a fancy zipper pull, completely harmless and unremarkable... to anyone who doesn't know.

"It should guide you in a direct line towards a target of your choosing, letting you refresh or change the target each night. Just concentrate on who or what you want to locate. It will do the rest." A person who Yondu cares for, has a bond with, will be the easiest to find while an inanimate object will give a more general direction.

Thanatos will place the keepsake into Yondu's hands at the first opportunity. "May it help you find whatever's important to you."
