Get their company.

With the poster in hand you slowly approach the elves' table, and you notice the rogue moving one hand to his dagger in precaution. When you're standing near them and both sibblings are looking at your face - or where it would be - you remember: you can't speak.

The rogue is the first to say anything "I- uhhh, can I help you?"

You should've thought about this before, but now it's too late. Luckly they didn't recognize you from the lake, probably due to your before faint and now opaque color. You lift the poster and point at the spot saying "lvl 20x2" then point at yourself and at them. They look at each other and you notice Rhiannon waving no with her head. Before you can protest, her brother speaks.

"Come on, sis, we need to train if we want to do anything!"

"No, Rhonnan! This is the kind of job Hu- hmm... our guard would never allow us to do!"

"That's the reason we were never able to fight to protect him! We need to be bolder to get stronger, sister, and this will never happen if we don't take risks!" he looks at you "Say, mutie, what can you do?"

You can't show your skills without a weapon, but you have an idea. You pretend to be thinking and fake a punch in Rhonnan's direction. The rogue immediately brings his dagger up and to your neck, one of the exposed articulations of your body. The dagger penetrates your head, bottoming inside your "skull" after a hit that would've killed anyone with vitals. They're both shocked for a moment, and even more when you back off, making him drop the weapon, and you pull the blade out of your own head, as if getting stabbed through your skull was a minor issue. It doesn't take much more convincing after that, but they're still confused for the rest of the coversation.

As you three walk down the street, you're **** to avoid gazes again, and consider getting some kind of cape to cover your body. But you notice that those looks aren't directed at you. The twin elves walk calmly drawing the attention of every smart being that looks in their direction, showing you how rich and famous those two must be. Despite that the three of you are able to leave the city without interference. The contract says the targets are a few miles west, in a chasm, but you're not in a hurry and walk slowly, admiring the sensation of being so close to people without fearing for your life.

You're lying on the grass overlooking the chasm, and can see the cave where your targets are supposed to be.
Rhia is arrogant. She likes to go by herself and risk being killed, if she underestimates the enemy - which she always does. Despite that Rhon is the one that likes to show off. And that will always mean "abandon the group to do what looks the coolest". Thanks to Galleon's Power Token you're able to read their objectives and strategies before even entering combat, and you know that they will need you. You could:

Help one of them, gaining their confidence and respect, but leaving the other to certain ****;

Could do it all yourself, and even show off while doing so;

Or you could also leave them to certain **** and then kill the targets. It would probably make them angry but, more important, you'd have all the loot - which you can somehow tell is a lot - all to yourself.
