It has been a week since they returned from the forest after collecting berries. They have already divided them among themselves.
Amon didn't have any use for Blue Berry, so he refused to take it. To balance it out, they gave him more yellow berries, which were the ones he needed most.
After they had divided all of them, only the purple one was left; at first, it was offered to Lyra.
However, Lyra refused; she said it was of no use to her. The creatures she summons already share a good bond with her.
Most of the time, she doesn't even summon the same creature twice. It would be a waste in her hands.
After this, it was the turn of Rydan; he was an excellent archer. Later, he might need a mount to become more lethal.
While Rydan said that this was all true, but he was a Dark Elf, it was not hard for him to create a bond with Demonic Beasts.
