@Risp: No, that won't be necessary.
@Xion: The base is part of the scenery. It cannot be destroyed unless it's part of the storyline or a cutscene.

L_G sits there on Snake Road, thinking about recent events. "As long as that Pylon is up, I can't go back home. It's time to pull out the big guns," says L_G. He takes out a piece of paper and scribbles a note on it:

Dear Beth and my past self,
By the time you read this, I will no longer exist. I have reached a roadblock in the future that's preventing me from going home. Surely you have heard of Strato and his Peep army; they set up a Pylon that's blocking interdimensional travel. There are powerful enemies guarding it; enemies that I cannot defeat myself. I must ask you to take my past self to the Shadow Realm, and use the provided Interceptor II to escape before Strato catches up to you. I wish you the best of luck.

Going to miss you in the future,
-Future L_G

L_G sighs. He was hoping it wouldn't come to this...
"No matter," says L_G. "I must do what I can to save myself."
L_G takes out the Ocarina of Time. He digs around the jumbled-up thoughts of his mind to find the one asong that can save everything:
C-Right, A, C-Down, C-Right, A, C-Down.
L_G tapped out the destination on his feet, and a time portal opened. L_G takes a deep breath, and steps through.

Somewhere back in the past, L_G appears out of thin air. He looks out into the distance, seeing nothing but mucky oceans. L_G shakes his head and says, "Risp and Strato shouldn't have com after me...now they'll pay dearly!"
Following the faint energy signal of his petrified self, L_G blazes across the landscape. It only takes a few minutes for L_G to find that he was not alone: Beth and her platoon have already arrived.
L_G flies up to them and says, "Hi."
Beth turns and gasps. "It...It's you! But how? I don't understand..."
"Allow me to explain," begins L_G. "I'm from the future."
