Here we have a demon dragon portal, it is considered black arts because all manner of dragon, demonic, that is, come forth out of it. It is a lovely hand made box i got here in Tunisia. It has been sealed with demonic power so you will need to break the seal before opening, I will send you the spell to do that upon purchase.

If you have never dealt with demonic entities before, and these are entities, then i advise caution before purchase. There is a guardian of the portal and I will send you his name as well, he will ensure no demonic dragons stay unless specified by you.
