Kreiss made a challenge on getting the gem first. The gem that Kreiss was specifically looking for was the family gem of their clan. He didn't know where the gem is specifically located, other than it being in a shed.
His uncle was the one who told him where the gem was. He also said that the gem was no longer important. The only question Kreiss has about the gem is why it was left behind. It was their family gem, so why was it hidden away? Why didn't it get passed on to him and why couldn't his uncle state the reason why it was left behind? Does it really have no use?
These questions were the reason why Kreiss decided to look for the gem. He's been wanting to take a look on the gem and now, he took the risk to look for it, involving Veon. He did not want to risk his life alone. He hoped that once he saw the gem, he will know why it was left behind.
