Nexus Vs Samya the mimic

Nexus was walking through the Forest of Attia holding a guilded poster. The poster was a bounty for a wyvern that had been spotted stealing sheep from the forest's edge. He was making his way to where the creature's nest was rumoured to be. Nexus comes across a fallen tree and ducks under to pass it. Will you move forward or investigate the tree?

Nexus was very new to this bounty hunting and was unsure of what he should do exactly. He ducked under the fallen tree and investigated to see if the tree was destroyed by anything or anyone.

Nexus looks at the markings around the split in the tree. Claw marks. There seems to be something lodged in the side of the tree. Does he investigate further or move forward?

Nexus is both a bit scared when he sees the scratch marks on the tree and knows whatever did this is a dangerous foe. He decides to investigate more to see if he can spot anything else.

The marks were definitely from a wyvern. This seems like a show of territory marking. As Nexus looked he saw one of the claws protruding from the tree. Does he want to take it?

Nexus was even more concerned and had thoughts of just heading back, but he was determined to catch this wyvern and decided to take one of the claws from the tree. It does look nice and even if he dosent find the monster, he’ll at least have something neat to have.
