Erend and Eccar had decided that they will to take on this battle personally. Of course, Erend always appreciated Adrien and Billy's help, however, he felt this conflict was different.
It was a matter deeply tied to the Elf Palace and Laston, and dragging his friends further into it felt unnecessary cause this was not their fight. They had already risked enough and Erend didn't want to burden them with this new threat.
He had already spoken to them about it, explaining the situation and his decision. Adrien had been understanding. Billy, on the other hand, had been visibly reluctant, the weariness of their previous battles still fresh in his face.
Yet, Billy's resolve to help his friend had not faltered, and he'd said with a firm tone, "If you need us, just call and we'll come."
Erend had nodded, clasping Billy's shoulder in gratitude, though he hoped it wouldn't come to that.
