Galenas

Faramir found Aragorn on the balcony, surrounded by smoke. Emboldened by curiousity, the Steward stepped next to the King and sniffed the air.
Aragorn removed the pipe from his mouth and extended his hand for Faramir to investigate.

“I understand this practice comes from the north. How does it work, if I may ask?”
“Yes, it was introduced to us by the Hobbits. You put dried galenas in the bowl and light it. Then you suck at this end. You may try, but do not inhale it.”

Aragorn smiled wistfully as he remembered how Halbarad had taught him this art so many years ago.
