With proper food available, who would eat Squig stew with mushrooms?
Eldar and humans not only looked very similar, but even their physiology was nearly identical. They were carbon-based lifeforms divided into two sexes, and their diets differed very little.
Whatever humans could eat or use, they could eat or use as well. It was only because their nerves and souls were more sensitive that they became extremely susceptible to addiction to certain things. That was also why the Eldar had fallen in the first place.
Alcohol addiction, drug addiction, smoking addiction, sex addiction—setting aside all the mental dependencies humans had, they could even develop corresponding "addictions" to enjoying fine food, listening to beautiful music, or sitting on a comfortable sofa.
If the ones on this planet had been Dark Eldar, Gunnar definitely would not have even glanced at their filthy pleasures.
But over the past few days, they had only fought white Eldar. They feared Chaos corruption more than any other creatures, which, in a sense, meant that what they ate and drank was definitely cleaner than anyone else's.
Using alien weapons, riding alien vehicles, wearing alien clothing, eating or drinking alien food and beverages—every one of those acts was blasphemous and heretical. If the Inquisition saw it, it would probably bring harsh questioning and judgment from the grey knights.
But the Space Wolves were not afraid of the Inquisition. It was not as if they had never fought them before.
During the Battle of the Month of Shame, the Space Wolves had lost quite a few men, and Fenris had been bombed into a complete mess. But the opposing Inquisition had lost four battleships, with casualties beyond count. Old Wolf had even hacked one Grand Inquisitor to death, and the grey knight force had nearly been wiped out.
