Tristan MacLennan was your everyday young adult struggling to support his poor family while keeping his terminal disease a secret, when one day while organizing the attic, he found a genie stuck in a family heirloom. Having made peace with his own fate, Tristan sets his family up for life and uses his last wish to free the genie; however, in a twist of fate, Tristan ends up a genie himself.
There's no way back, and the weight of eternity hangs over him. Tristan must get stronger and smarter if he has any chance of holding his own as a magically indentured servant in an increasingly callous world.
What to expect:
Character growth: Tristan starts the story ready for his own death, and then quickly has to deal with becoming functionally immortal, and completely out of his depth in the suddenly magical society he's now a part of.
Light system elements: there are no blue boxes in this one but numbers definitely go up, and in a unique way: Tristan is a genie and grows and specializes by granting wishes.
Adult problems: the supernatural world is cut-throat and Tristan is not an all-powerful being and neither are most of the cast. Expect combat to be common, but not to be the end-all for solving problems. Warnings are there for a reason.
What not to expect:
Harems, unearned op power-ups; the main character being the smartest, handsomest, strongest chosen one.
