Battle Royale: A Wizard's Challenge!

Invitation: Gathering of the Strongest
"Hmmm..." An elderly man sat across an expansive stadium. Well, not across, but rather, in the center. He, with his student, sat in the middle of this enormous stadium. The stadium was painted with numerous coats of thick white paint, and ornate by other coats of varying, darker colors. The four corners at which large poles stood to fortify the rectangular-shaped stadium each had a specific decoration, reflecting that of the four cardinal directions. The east pole possessed an azure, draconic figure slithering and climbing across the pole; the west held numerous white tigers climbing to the top of the pole; the south had a bright, vermillion phoenix dancing across the pole with her feathers separating from her being; and the north was ornate with several purple shell-like figures. It was fitting for the occasion that would be about to occur.

"Are you sure about this, Master Harry?" Lyon asked, raising an eyebrow at his master's intentions. While Lyon wasn't shying from a battle, Harry's sudden request for a battle royale of this kind...something dubious was indeed aboard. "Of course I am sure, Lyon. Do you doubt your old master's intentions?" Harry responded in an inquiry, to which Lyon was abashed ever-so-slightly. "Uhh...not at all master. However, uh...what prompted you to take such a step?" Lyon asked once again, to which Harry took another sip from his cup of tea. "Well, you see. I'm an old man. And an old man has a much higher chance of dying than a young man, depending on whether they have a relatively low-profile occupation. Now, I am a Wizard Saint. If I leave my position without any proper successors, what would that make me? Now, I understand that you are a primary candidate for me, however I also understand you aren't exactly compatible with the nature of a Wizard Saint. Therefore, this is what the Battle Royale is all about."

Harry responded to him with great detail, before sipping again from his teacup. "Oho! Our guests are here; please make them feel welcome, Lyon." Lyon, while still mildly astonished from the answer, looked towards the large stadium gates. Painted in a sheen of glittering silver, and ornate with numerous patterns of insects, smaller mammals, and magical designs: it opened.
