SkunkyArt | OneBadPun — First Friend!

Scorpan was Star Swirl's first real friend!

Despite being bigger than them (and most ponies) Scorpan is younger than the Pillars.

After Tirek's imprisonment, Scorpan had returned home to tell his parents the news. But after that, he had returned to Equestria. By the time Scorpan came back, Stygian had already brought the Pillars together to defeat the Sirens, so Scorpan wasn't around for that. Scorpan reunited with Star Swirl and became friends with the other Pillars.

Scorpan helped the Pillars create the seed that would become the Tree of Harmony, but asked Star Swirl not to record his involvement (for unknown reasons).

After the Pillars sacrificed themselves to defeat the Pony of Shadows, Scorpan returned to his homeland once again.

Scorpan had found Spike's egg by itself in the middle of nowhere, and decided to take it with him. Scorpan decided to give it to Star Swirl, who gave it to Celestia and Luna. This is a reference to Generation 1 obviously.

The same way the Mane 6 got their elements from the Pillars, Spike got his element from Scorpan.

Scorpan's friendship with Stygian is similar to Spike's friendship with Starlight Glimmer.

Years after the Tree of Harmony grew, Scorpan returned to Equestria to take a branch from the Tree, and created the Staff of Sacanas.
