After handling the emergency at the medical station and fixing a poor soul's missing nose, Durin, along with the young female dragon Lina, set fire to the Green-skinned Orcs' camps around the fortress.
The Green-skinned Orcs had never seen such a relentless tactic and were driven out of their camps by Durin's fire in this icy and snowy weather, likely giving them quite the struggle.
After setting the fire, Durin returned to the fortress—having come all this way, he hadn't planned on going back today.
So, while the other Silver Dragons started to return, Durin concealed his aura and sneaked into a small room in the fortress's High Tower with Lina.
This room was originally a storeroom. Durin burned the miscellaneous items, cleaned it up with a Spell Formula, and then pulled out a bed and a small bookshelf from his space.
Of course, there were also several big bags of snacks.
The little female dragon, Lina, cheered and hugged the bags of snacks to show off.
