Rekal Aari

Rekal Aari is an elven planeswalker from Tuopoto who works as a mercenary. His powers lie mostly in his sheer physical strength, speed, toughness, and creativity. They are mostly nonmagical in nature, but not entirely: for example, he has been shown to be able to cast healing spells before.

Early life
The first time Rekal became captain of a small mercenary squad was 7 post-Mending, Month 1, Day 24. After his squad disbanded, his spark ignited.

The Arena
After he learnt about the existence of the Arena, Rekal became a frequent visitor of the plane in his free time to fight there for pleasure. Other planeswalkers came to know about this, and often visited the plane to hire him because they knew they would find him there.

Through various intermediaries, Rekal was hired by a sentient hat from Rhak to bring Okus Pokus a letter from home asking for news, along with a package of gourmet hair. He successfully carried out the task, more or less on accident, without learning that Okus was possessing Karina Oblay at the time. Okus was unable to read the letter immediately because Karina didn't know how to read at the time, but since Karina was eventually taught how to by Reyhsia, Okus eventually learnt about the contents of the letter.

Rekal was hired by the geomancer Aylin to attempt to kill her seven times there in the Arena. However, after a few attempts, involving leeches and ox throwing among other shenanigans, Hyle Seritani hired Rekal on behalf of High Builders to fight against the Arm of Cruelty on the plane of Eilei and took on herself the responsibility of carrying out the remaining attempts at Aylin's assassination instead.

Eilei
On the plane of Eilei, Rekal cooperated with the mermaids of Lagan Tantid and killed Ak Zur, the leader of the Arm of Cruelty, by driving a sharpened burning tree trunk into his eye while the mermaids distracted him. The loss of their leader drove back the Arm of Cruelty for a time. Rekal was then hired by Heldra and Alastor to fight Lindri on the Arena, where he returned along with the two of them and the High Builders.

Back to the Arena
Upon returning to the Arena, Rekal filled Hyle in on the recent developments on Eilei. He met Khon Vasq and put him in contact with Heldra, who recruited the Phyrexian to fight Lindri. Rekal wasn't present for the final battle against Lindri.
