Veofum

Veofum was the castle lord of Jan's Kingdom. He ordered his men to burn Xerneas as the attempt to bring fertility to the land. Jan tried to stop him from but Veofum didn't listen. Instead, he met his demise by Zygarde, who was enraged they would burn down Xerneas. Zygarde destroyed Jan's Kingdom with Land's Wrath, sparing Jan's life and putting out the fire.
