Thought you'd gone! Well, it's ok if you're not keen on the towers, because we've since come up with a new idea. This is probably the best way to explain it:
Imagine a wheel (I.e a big circle with a small circle inside, which both share the same centre). In the small circle is a crystal (preferably shining). The area between the large and small circles is split up into 5 parts of equal size. They are in the following colours: one purple, one red, one green, one yellow and one a very light shade of blue or gray. In these sections there are, respectively, a Mewtwo, Ho-oh, Rayquaza, Arceus and Kyurem. As you've probably guessed, these represent the 5 divisions. They'll also be a gold trim/line splitting up the sections. The line of the circles should be the same colour. The text "The Crystalline Guard" can go anywhere, and can be in any font, see what you think looks best. I'll have to agree with it though.
Does this sound do-able?
