Probably a terrible idea.
Old Man Henderson had been missing for some time. Since that debacle with the "civil war" and whatnot, around that time. Last we saw of him, he was fighting a horde of losers in some private army, it was pretty awesome. So now, here he is, back again from what we assumed was hell to stir up more trouble. He's conversing with some eldritch abomination, while also having a shotgun pressed against the thing's head. What a cool guy.
You are outclassed in this realm, old man. Power like yours is more common than anything else here. You are NOTHING.
Henderson wasn't having any of it, and simply blasted the thing without a second thought. That's another one of those damned things off the list.
"Well, if I'm nothing special in your eyes, then you're even less...or something. Still, I can't really say there ain't a lotta strong guys here. I'm sure it's fine, but it'd be nice ta have a way to prove it."
Henderson turns to the stuffed parrot sitting on his shoulder, nodding and seemingly carefully consider everything the totally sentient parrot told him.
Now there's an idea. Alright Rupert, let's do it.
Taking a sticky note from his cargo shorts, Henderson writes an add out using the creature's blood. A space was even left on the wall for people to write their own names. Surely nobody will clean it up.
OLD MAN HENDERSON'S TOURNAMENT OF POWER.
"Two weeks from today should be a good date to do this. Alright, that's enough for today, let's go get wasted."
With that, he leaves. Feeling satisfied, and thirsty for the thrill of battle.
