First an introduction to what i am doing! I am creating a tool for players and DMs of D&D. The reason i've been trying to understand the copyright law in regards to this issue is that upon using any information from the books created by WotC you'd violate their copyright. Luckily, WotC has a "Open Gaming License" that you can use, to have much of the rules, items and monsters in your book, program, etc. for free (Link to the link of the SRD-OGL: http://dnd.wizards.com/articles/features/systems-reference-document-srd)
My issue is that WotC has intentionally left out some of the unique monsters that they themselves has created over the years. Which in itself is fine, but i have no idea if i would violate their copyright for these unique monsters if i were to create a module in my program where the enduser would be able to build a custom monster from a blank template (name: input here, armor class: input here etc. - you can look at an example on, say, page 279 with the Tyrannosaurus Rex. Here name would be Tyrannosaurus Rex and Armor class would be 13 (natural armor))
If the enduser were to create a totally custom, madeup creature i'd imagine that tool would be fine, but i can also see the scenario where a enduser could copy letter for letter the information of a copyrighted monster into my custom monster template and essentially adding a copyright-violating item into the program.
So. I guess in essence what i am asking is: By making a tool in my program that can enable the user to create their own monsters, will i then be in trouble because i've also, if the user is malicious, by extension enabled the user to violate the copyright of WotC?
I am from Denmark if that makes any difference, which i'd guess it doesn't. I have no real legal experience which is why i thought it'd be a good place to ask such a question. Thanks for your time!
