Noel longs to be a Seeker like his heroic grandfather, slaying the beasts that emerge from Abysses and exploring far-off lands.

Undaunted, Noel sets out to establish the strongest clan in all the land, using his silver-tongued Talker skills to unite assassins and heroes under his leadership. (Source: Seven Seas Entertainment)
