One of my favourite memories of the vault is staying on, when the rest of my clan had gone to bed and just chilling out on patrol in front of the vault, sniping at vex from the top of a pillar and just taking in the scenery. One of the plates hums to life and that unmistakable sound of the vex machinery clunking as a raid begins. I aim down icebreaker's scope at the left plate and, sure enough, see a team beginning the raid. I quickly switch weapons (pulse rifle to aetheon's, icebreaker to found verdict, and machine gun to gjally) and head over to enter the fray. I quickly weigh up the situation (who looks like they're struggling, are there any guardians down/out of position) and, more often than not, take up my position bolstering the left (bottom plate). Sometimes others sparrowing though on patrol join in, sometimes no-one comes by for the (seemingly) short time it takes for the shimmering sound and series of clunks that signify the door opening. I rush to the door, waving to each guardian as they enter, and they wave/dance/point in return. Sometimes i'm invited to join due to shortage of numbers and i happily accept. Sometimes the fireteam is full but that extra body has helped make the opening of the door a bit less painful, and that knowledge is all the thanks i need. For all i know this may be the fireteam's first foray into the hidden mysteries of the vault and i've helped them begin their adventure or it could be their twentieth and i've helped save them time and get the door open straight away, it doesn't matter. The ability to do this was sadly missing from Crota and Oryx, and i think may be an element that contributes to the enduring legacy of the Vault. The opportunity that having the Vault entrance accessible on patrol gave meant that you really never knew how your night was going to end up, and I think that that unpredictability was part of the magic of the early days of destiny. I hope it returns.
