I might remain

Q: How does one contact Chronos?

I’d suggest e-mail. There is a little icon below each of his posts named e-mail. Click it and you will be taken to a page that lists his e-mail address. BTW, this question would be better served in ATMB (About This Message Board).

I really surmised that.
You left out Strontium and Tech.
Also, heavy water.

Later.
