There were two types of these Spanish Wizards. Those that gained power through black veil and those that gained it through years of intensive training and the conjuring of the most powerful beings.
They both were able to see through things to gain power,knowledge and workable magic. If they would visit a museum which held something powerful they could gain that power. I'm using a museum as an example.
They could go to homes of those that held magicals and gain the power of them. This does not mean it was stolen but that it was duplicated and made even stronger.
This wizard is called Car Valdespino. The power goes beyond what I have mentioned. When he is in the home you take him when ever you tavel or want to gain magic. I have used him for the bible code, At graveyards in Salem, and in various places in New England. I have also taken him with me to places of pure power.
When using this item it is as if you have a million pieces in one. The more you use it the more he gains in power. It could end up being your one and only piece that you build.
A little like Build a Bear except it is Build a magic.
