The Seastone Tower.

The Seastone Tower: Synopsis.   Kelen Vance once had it all. A promising apprenticeship in the Seastone Tower, a life of luxury, honor and friends he held dear. Erebus the Treacherous changed all that. Burning his Tower and forcing his deepest secret out into the open. Kelen now struggles against the Fiends within the Fell Wound’s southern front. Taking advantage of the chaos and clawing at every opportunity, commission and sliver of hope in front of him. With the goal of one day following in his grandfather’s footsteps and regain his place in the Seastone Tower. That goal seems farther away than ever when he finds a young man from another world, who seems to think himself a hero. Will Kelen manage to turn this to his advantage? Or will the so-called hero get him killed? - This is a story that's closer to the traditional fantasy, only with the MC being a friend / mentor to the one getting Isekaid. I thought it was a unique enough idea to explore and it turned out pretty well.
