The ideas are just there to jog your mind. Feel free to take both of them, parts of them, or none of them. Cobble them together into something you'd like to play.

As I was rereading the listed ideas, I realized they're not mutually exclusive. So if you like both, you could do both. Your character could be isekai'd here, start as an adventurer, discover her love of the forest and grow into her calling, and maybe unlock animal powers along the way. And once she gets to know the forest well enough, she might discover it's being plagued by Void infestation and take upon herself the responsibility of cleansing it. And once she takes her mission beyond the bounds of the forest, it might take her into the borders of warring nations, where she may try to serve as a mediator.
