Fate/Grand Order

A hero of the Celtic legends of Ulster.
A member of the Red Branch Knights and the most formidable warrior of Ulster.
He's the hero who wields a lance inherited from his mentor Scáthach, lord of the Land of Shadows.
He is also a formidable user of Runes - a magecraft based from Norse legends.

When he materializes as a Caster, it is different than when he materializes as a Lancer.
He uses a diverse range of magecraft to torment his enemies.
Specializing in powerful attacks using heat and fire, it is assumed that he uses the "Ansuz" rune letter.

Rune Spell: A
He possesses North European magical crests called runes, given to him by Scáthach. By using them, he can create powerful and diverse effects.
However, he cannot use multiple runes at once.

『Wicker Man』
Rank: B
NP Type: Anti-Army
Cage of Scorching Flames. A giant consisting of countless thin branches appears. The giant sets itself alight, and attacks the enemy to deal powerful heat and fire damage.

The cage in the torso of the giant that appears as a Noble Phantasm is empty, as a result the giant rages on, seeking sacrifices for the gods. This is not an arcanum of the runes, but a Noble Phantasm the Celtic druids gave to the Son of Light who materialized as the "Celtic Mage" controlling fire and heat.

When he materializes as a Caster, it is believed he imposes the role of a "guide" to himself. Not as a true druid but as a temporary one... As long as they are together, he will continue to guide and illuminate the path his Master shall walk on.
