Silver Age Remainders

Hawkman Special #1, from 1986.

As the Crisis on Infinite Earths drews to a close, this was released to finish telling a tale from before the Anti-Monitor gave the Multiverse the finger. In a surprise turn toward the good (you could tell things were going to hell), the Gentleman Ghost joins with Shayera (Hawkwoman) to guide Katar Hol on a sort of Thanagarian spirit quest, in which he helps to bring peace to a group of Thanagarians Hawkman had to kill to prevent an invasion of Earth One.

Interestingly, a Hawkman monthly title debuted shortly after this, bringing us a year or two of stories of the pre-Crisis team of Hawkman and Hawkwoman, before the seriously-rebooting Hawkworld mini-series debuted.
