nothing much as of yet
harry has a way to beat voldemort in the battle of hogwarts that he planned in secret from his friends and Dumbledore having realized that he would never get to have a life if things went on as they were even if he won he would be the boy who lived and won or some other stupid moniker he would never just be Harry he would always be famous a public possession loved one moment hated the next the scapegoat for everyone's problems never good enough so when he found a spell in the room of requirement after Sirius died it seemed perfect he just needed to prepare but knew no one would let him do it if they knew they'd claim it was because they loved him and didn't want him to risk it or didn't want him to leave cause they'd miss him or that it'd get better or some bull like that but he knew that in the end they wouldn't listen to him that he'd had enough and just couldn't give anymore so they'd do their best to stop him and probably succeed.
the spell he found in the ror would send him to another world but it had requirements to be cast one of them being a sacrifice and normally that would make it a dark spell and he wouldn't touch it but the sacrifice for this spell had to be corrupt and against the balance of the world the more vile the sacrifice the more powerful the spell but it didn't just judge the sacrifice in this way it also judged the caster such that they could fail to leave despite the sacrifice if they didn't meet the requirements but he felt that he would almost definitely succeed for as evil as voldemort was and how much he'd been targeted and lost it was practically a guaranteed success and with those kinds of conditions he might just qualify to leave with everything he has on him the passing line wold let him leave but take nothing after that the next rank of passing he could keep his clothes but nothing magical and so it went each rank of acceptance he would get to keep more, he would try for everything anyway he had nothing to lose by doing so
so he goes to the goblins in secret to get everything he can get prepared and also healed but also not as being healed would risk his plans being revealed so only the potions and some ritual instructions were to be prepared
he warns the goblins before his break in and is able to pick up his prepared to go trunk containing his entire worth mostly converted into books as well as other things of value such as enchanted items and enough seeds and animals to jump start a magical world and if needed a muggle one as well with only minimal gold who know what the monetary system will be in another world, plus some houselves who couldn't find work in new families so joined him he wished he could take them all but it's unknown if they'll be able to follow him and very risky if they couldn't get a new family if they ended up being left behind
it would be awesome to have him end up on a Zerg world
he would be a precious male and get lots of love ❤
look on mtlnation.com and search zerg most of the options are viable
though there is the option to have him accept a harem
he might not be happy due to the attention drawn to him for nothing else but being male but it wouldn't be the same he also wouldn't be the only one nor be made in a scapegoat or hero it'd be attention he could deal with
