Valgard
From Tardis Wiki, the free Doctor Who reference
Valgard was one of the Vanir on Terminus. He challenged Eirak's leadership, who agreed to step down if Valgard would bring the Doctor back from the Forbidden Zone, which he eventually succeeded in doing. He and the other Vanir were freen when Nyssa offered to synthesize Hydromel for them. (DW: Terminus)
