Halcyon™ 

Just a passerby who you'll either come to love or hate (or neither). He's cooler than boredd and to be friends with him requires a lifetime's worth of luck. He prefers honesty and transparency.

Halcyon™ is a nice friend to have.

Halcyon Days 

Almost literally means the "calm before the storm", but can also be used to signify joy, tranquility, etc.

Goodbye Halcyon Days.

Halcyon 

An all around great person who is always willing to listen and checks in on you. They're an amazing person and be happy if you have them as a friend. Their name shows their uniqueness and individuality. As well as their peacefulness that they hold.

Damn hanging out with Halcyon was so nice. I gotta hangout with them more.
