Would be nice to be able to teach them in small groups, likewise for people to be able to absorb knowledge while they slept. As someone who used to have to civilise successive waves of the raging barbarian hordes 40 to 50 at a time in NSW State High Schools while I taught science, maths and real life for 19 years I can assure you that it's a bit tougher when they're awake. Cheers Ed.
Speaking of nice worlds, it did occur to me to wonder whether Cyeateans ever suffer from any kind of substance dependency/addiction problems. Not sure why my mind went there, but I thought it would be an interesting question.
