By the way, if you're still wondering if you should release it or not, I say that you release it.
Open Tibia was built on the precipice that it's an open source project, a community that feeds each other and helps each other. If you would release this, yes, there will be ungratefulness/those who try to steal credit or don't even say thanks, etc. That's simple human depravity these days. However, there are those that will not only LEARN from what you've done, but it really would inspire others to make enigmatic and creative creatures such as this one, a section of open tibia that has been seen as stale/gammickey.
