This isn't really going to be that big of a deal. No backstory, no deep character examination, no role-play specifics; if you want that, visit my other builds. I don't plan on ever doing a casual build description like this ever again. I just wanted to create a Warden that accurately resembles the abilities, play-style, and aesthetics of the class from the game.
Race: Imperial is best, in my opinion.

Playing as a Warden requires using the Block Skill and Power Attacks intelligently and effectively. When entering battle, use your "Catapult" Feat (Fire Rune) to lay some hate and stir up some chaos, then charge in with a sprinting power attack on the weakest opponent you can single out. Work your way through your foes from weakest to strongest for the most authentic experience of honorable combat. If set upon, it's a good idea to make use of the Quick Reflexes Perk and move around your opponent as they swing at you. It's best to bring a follower who best compliments your play style, such as a sword-and-shield character, for the teamwork aspect. If a battle gets too rough or goes on long enough to justify it, use your Fire Rune to do some extra damage to your enemies, or even break out a Restoration spell like Close Wounds and Heal Other to bolster yourself and your companion, or even Grand Healing, if you have the right amount of Magicka. For this effect resembling the "Stalwart Banner" Feat, though, it would be best to just have the Waters of Life Power from the Water Stone on Solstheim and reacquire it before anticipated battles. If you manage to level the Restoration skill at some point in your playthrough, you might also consider getting the Avoid Death perk to resemble the "Second Wind" feat, or even using the Bones of the Earth power from the Earth Stone to resemble the "Thick Blood" Feat: I've tested it, and yes, it does protect you even more with armor on.
