Since all magical creatures generate interference (AKA disruption) only humans can be true techans.
Gimfen don't radiate an EDF (Enchantment Disruption Field) but it is still tricky for them to use technology. Keep reading, it's all explained in detail (I sure as hell hope)

Humans are the only ones that can really decide to be either techans or echans. Gimfen could as well, it's just really uncommon.
Hope that answers your question. Any more, just shoot my way. As you read through the races section, it should be a lot more clear.
I am glad the softcover looks good, and I appreciate the thought of upgrading to the hardcover. However, please note that if you had ordered the hardcover, you would still be waiting.

It takes six to eight days for Lulu to process a HC and it still takes two weeks to ship. My softcover will be here next week. The HC is probably still two weeks away

I also hope you will spread the word, post reviews, and tell others.
