The tenants of the Oath of Winter's Wrath emphasizes the cold and unforgiving nature of winter.  The four central principles are simple.

• Cruelty. Compassion makes you vulnerable. Let Cruelty be the knife that keeps your enemies at bay.
• Endurance. Exist as long as you can, by whatever means you can. Only be enduring can you outlast your enemies.
• Isolation. In solitude you can understand and harness your full potential. Depending on others makes you weak. 
• Preservation. Every snowflake is unique, and that which is unique must ben preserved.
