Sebastian will be out there somewhere in the Peaceful Hills. Once he realizes his feed trough is full, he'll make his way back here at his own pace. Letting him smell you should be enough.

Mine Shapestone Ore

Perfect! He's slow, but I'm sure he'll be back here before too long. Next, I'd like you to MINE some SHAPESTONE ORE. When in BUILD MODE [HK:SwitchInputMode], you can MINE by holding [HK:BuildModeDestroy]. Finding the ore should be easy, as it's bright pink in color--be sure to check any caves, caverns, and crevasses you come across! Use [HK:SwitchInputMode] again to switch from Build Mode back into Adventure Mode!

Craft Sebastian's Shoes

Return to me with that Shapestone and you'll be able to craft some Horseshoes for Sebastian! Once here, use the Horseshoe Forge. Check your Hotbar [HK:AdventureModeSlot1] and [HK:AdventureModeSlot2] or Inventory [HK:Inventory] for a Origin Portal Potion to make your return trip quicker!

Mount Up

Now that good ole' Slow Sebastian is ready to ride, he's all yours! Mounting is simple, just use [HK:EquipMount]! I can tell you two will be fast friends!

Now that good ole' Slow Sebastian is ready to ride, he's all yours! Mounting is simple, just tap [HK:Move]! I can tell you two will be fast friends!

Claim a Cornerstone Plot

Now is the perfect time to learn a bit about building. You can do that here in the safety of the Peaceful Hills. Simply find a CORNERSTONE sign and interact with it using [HK:Loot]. While you can build in most places, each Trovian gets their own Cornerstone, where everything they build is saved! No matter what world you travel to, your Cornerstone will always be with you! You can summon your cornerstone by finding an unused Cornerstone plot, denoted by a yellow '?' signpost.
