Tyvar Kell

Tyvar Kell is a black- and green-aligned elf planeswalker from Kaldheim.

Appearance and characteristics
The younger brother of King Harald, uniter of Kaldheim's two groups of elves, Tyvar is a confident, charismatic, and pale-skinned wood elf. He sports a muscular frame and long, braided auburn hair. He rarely wears a shirt, exposing his powerful physique and distinctive tattoos of Koma, the "cosmos serpent" of Kaldheim, whom all elves possess a shared reverence for. The tattoo's twin dagger shapes and the double-bladed sword he fights with each represent the snake's fangs. He loves to boast, always on the hunt for glory and the admiration of his peers.

Though he's certainly preoccupied with building his own legend, Tyvar has a peculiar relationship with fame. After an epic battle, he's just as likely to sing the praises of his allies as he is to brag about his own achievements. He's really a classic extrovert at heart who enjoys the camaraderie shared among warriors. He actively seeks out allies willing to fight by his side and share a drink to celebrate their glorious victory afterward. Tyvar is a formidable close-combat fighter. His weapon of choice is a two-bladed sword.

Tyvar is able to transmute natural substances (including his own body) into other close-by natural materials, letting him use the environment to his advantage in combat in a special way. Deeply flexible, this ability greatly helps with improvising during a battle; he might coat himself in stone or thorns for protection, or in the inverse cool molten rock to a solid or make nettles sprout from the ground beneath his foes. Tyvar's abilities are very flexible but limited by what kinds of natural terrain are immediately at hand. This makes him a natural improviser in combat, and he relishes the creativity battle requires. Tyvar's powers aren't limited to himself, he can also share these buffs with his allies.

He has stated his power works differently depending on the plane he is on. He also isn't always aware of how his power will work until having tried it. Kaya notes his powers are that of a transmuter, but unlike one she has ever meet.

Kaldheim
Tibalt (disguised as Valki) visited Harald and advised the King to prepare his army for the coming war. Suspicious of this "Valki", Tyvar began to follow and investigate the god through the realms. When Tyvar arrived at Gnottvold, he found Kaya surrounded by Torga trolls woken by Tibalt. The elf helped Kaya by defeating the trolls, turning them into stone. After Tibalt escaped to Immersturm, he opened an omenpath to that realm. At that moment Kaya discovered a small hedron from Zendikar hanging around his neck. Tyvar had believed Zendikar to be a distant realm from Kaldheim itself, and Kaya had to explain that he was in fact a planeswalker. Together the two decided to work together to investigate and stop Tibalt's plans.

The pair followed Tibalt to Immersturm where they were accosted by a couple of demons. Because of this, they were unable to prevent Tibalt from creating a Doomskar. Lead by Varragoth, thousands of demons streamed through a giant rift in space to attack another realm. Kaya felt defeated, but Tyvar persuaded her to stay and fight.

In Bretagard, Tyvar, Kaya and the leaders of the Clans were advised by Alrund to take the Sword of the Realms to Halvar, so that the god of battle could end the Doomskar. Mounted on a giant raven Tyvar, Kaya and Arni flew toward Halvar, but near the destination they were attacked in midair by the demon Varragoth who wanted the Sword for himself. Kaya used her powers to save her companions from certain death, but they ended up falling close to the Dread Marn, Karfell's army. Arni stayed behind to slow down the zombies while the two planeswalkers would take the Sword. In the middle of the way Tyvar heard the sound of the horn of Skemfar's army and separated from Kaya to warn his brother of what was happening. Tyvar explained the situation to Harald, who decided to help fight the invading army and help deliver the Sword to Halvar. Near the location of Halvar, Kaya was attacked once again by Varragoth, but was saved by the elves. While Tyvar and the army of elves fought the demons and zombies, Harald helped Kaya to reach Halvar. Tyvar used his transmuting powers to strengthen his allies and hinder opponents, and tried as hard as possible to stop Varragoth, but the demon was only stopped by Kaya who cut the demon's throat with one of the axes Tyvar had made for her. After the great battle and the end of the Doomskar, Tyvar met Kaya and praised her for killing Varragoth and promised that the skalds would not forget any detail of this feat when telling this saga. He told Kaya that he now was ready to walk the Multiverse and help those in need on other planes.
