This is that kind of domains high valuable only if developed.
It's a nice one word, with 74,000 searches/mo and 3,400,000+ results on google, but the .org kills it a little. It doesn't fit very well with the word "invasions", that has a commercial connotation, like brands or music bands.
However, even if undeveloped, i think you can sell it into the domainer market for mid-high $xx, little more with some luck.
