Lina

Lina, Dennis and their colleagues , Jake, Jacob, Bertram, Caroline, Casper, Ahmed, Theodore and Joanna Elkmann spawned in the Tutorial together. He and his group joined Richard after Jake left, They were separated by Richard into other hunting group.

Jacob mentioned Lina and Dennis were supposedly ambushed by Hayden's members during negotiations with said group, but they claimed that it was not them, so it could most probably be William Hanson's deed. This occurred even before Jake made out of his Challenge Dungeon.

The Malefic Viper mentioned that Dennis, Lina and Jake would have died on their first night's watch in the Tutorial if not for Jake's Bloodline anomaly.
