Illegitimate Heir: Remembering Who You Were. Becoming Yourself. Staying Yourself

When you achieve everything you could, you become bored and start to take risks, playing with fate. And one day fate turns its back on you. Such an unexpected, shameful death, but it's all your fault; you played too far.... But as it turns out, you don't really want to die, and in your last breath, you invoke a ritual that has long been prepared for just such an occasion. And now you are in the body of a bastard of an ancient lineage, who seems to be completely ignored by all your relatives. However, your origins are far from being ignored by your classmates, and something unhealthy is happening in the Empire itself, but you have the memories, knowledge, and skills of your past life, which means you need to try to become who you were before, or someone very much like that - only then will everyone begin to take you seriously.
