We've seen many requests of people who want the band to perform in certain countries/settlements. But the band doesn't plan their tours themself, this is done by their concert management.
If you want to see the band at your preferred venue/festival, contact it's programmer/manager and ask him/her to take a look at or book the band. It's quite likely they want to know how the band sounds like, so direct them to the soundclips at tristania.com.
Tristania's concerts are being handled by Continental Concerts.
