Dont see too much in the way of 5e sci-fi material atm, so the release of this 'teaser' from the publisher is a welcome change to that status. This is very well written, with enough rule changes to allow the mini-adventure in the back (yes ... a mini-adventure) to be effectively run. The back story behind the timeline jump is convincing enough to see where many of the existing D&D line can fit in, including monsters such a Illithids, Beholders and on a more mundane level, Dragons.
This style of setting is definitely reminisent of a Shadowrun setting and I'd be very interested to see where further the 5e version could go.
Well worth a look at, and looking forward to seeting more!!!
