Good News Everyone!
Ash Law is going to write a group of related 13th Age Roleplaying game adventures that include planar travel! This is going to Epic.
You probably know Ash from the Midgard Bestiary (13th Age Compatible), Deep Magic (13th Age Compatible), 13th Age: The Archmage's Orrery, 13th Age Bestiary, Lions & Tigers & Owlbears: The 13th Age Bestiary 2, and so many more.
It's early days yet (we don't even have a name!), but this be will at least 25,000 words of breathtaking adventure. It will be one book with at least two different adventures (one champion, one epic). There will be a new area to set your own adventures in.
We're going to do all that. But wouldn't more be better? We thought so too, so in April 2018, we'll do a Kickstarter to see if we can add more adventure, more art, more monsters, and more excitement.
And take your players to another plane.
