Pyros

Pyros is one of the four Elemental Titans of Pagan. He is the Titan of Fire, and also the most dangerous one. He also rules over the Daemons of Pagan. The school of magic connected to him is Sorcery, the magic of fire. Pyros is like all four Titans, a servant of the Guardian. The Avatar puts an end to him in Ultima VIII.

Like all of the four Titans, Pyros became powerful when the Guardian tricked the Pagans to make them powerful through numerous means. In the war against the Zealans, he rained fire from the sky, and lava-covered vast areas, before assisting the Guardian into mostly destroying the world.

However, after the Guardian moved on, he came into conflict with the other Titans, but primary Hydros, Titan of Water. Pyros demanded high prices for not devastating the land, but still on occasion let the volcano break out. At one of these break-outs, Daemon's Crag came into existence. It ended, when five Theurgists, who later would became the Sorcerers, trapped him with the help of the Tongue of Flames, forcing him to lend them a part of his powers.

Now, Pyros only wanted revenge in his rage over such an act against him. He had time and could wait... Centuries went past, until finally he saw his chance. When the Avatar placed the Tongue of Flames on the great pentagram in Ultima VIII, he was free! Pyros laughed in dark happiness, while letting the volcano erupt. But his happiness was only short lived. The Avatar confronted him in the Ethereal Void, and used the Tongue of Flames, to drain him of all power, destroying him once and for all.

Trivia

 * That Pyros appeared in Ultima IX, can only be seen as one, big error.
 * Pyros is also called the "Daemon King" (no wonder, considering his looks).
 * The dynamics of the Titans is explained by Vardion. Pyros likes his brother Lithos. He hates his sister Hydros. And his sister Stratos, he has no quarrel with.
 * Pyros also resembles Guardian slightly.
