Welcome to Gaia! ::

Awesome! Four musicians under one roof, that should be interesting XD (And feel free to jump in the RP [Equestria!] at any point, just read the rules first lol)

"This good, Amy?" Lyricalana asked her best friend, referring to her with her nickname as she showed off the envelope she just decorated. It would soon contain an invitation to their Hearts and Hooves Day party, and she wanted it to be perfect.
Amoretta looked over the envelope and grinned, then used her magic to start decorating several other envelopes exactly like how her friend had done her's. "This is perfect, Lyric. Thank you so much." she said, putting each envelope under the ceiling fan so they would dry quicker.
"No problem. This one's dry, so can I put Pinkie Pie's in here and give it to her?"
Amoretta murmured something about 'Just marry her already...' before answering with "Yeah, that's fine. Can you take Rainbow and Fluttershy their invites when you get back? The envelopes should be dry by that time, and I already promised myself I'd take Twilight Sparkle and Applejack their invites."
"Absolutely. Thanks, Amy! Be back soon!" Lyricalana said, putting Pinkie Pie's invite in the envelope she just decorated before sealing it and trotting off to find her.
Amoretta groaned once the door was closed, but went back to decorating envelopes so she could take her mind off of it. "I can't believe I'm losing my best friend to a party freak..."

"... Where could she be?" Lyric murmured to herself as she looked around Ponyville from the skies from her close friend. Finally, she spotted a familiar curly mane bouncing away from... Discord's statue. Of course. Being reminded of how Pinkie Pie felt about Discord made the blue pegasus's heart hurt, and she felt as if she had already been rejected even though she never dared to speak to anypony about her feelings for the pink pony. Deciding not to let this kill her mood, she wiped away the tears she felt on her face and made herself smile again before swooping down to land right next to her friend. "Hey, Pinkie... I've got something for you." she said before pulling out the invitation she hoof made especially for her.

"... Aww, Pinkie Pie, you didn't do anything wrong. It's ok. If it, helps, I'm kind of having the same problem myself..." Lyric responded, thinking of another pegasus she had slight feelings for. She her head to get these thoughts out of her mind before turning back to Pinkie Pie; "You know what would help the both of us feel better? You coming to Amoretta's Hearts and Hooves Day party. That card I gave you is an invitation, and I really hope you can go. ... Also, maybe you can help me find Fluttershy and Rainbow Dash to give invites to them, too." she said, finding herself lightly blushing at the thought of RD even though her dark coat hid it very well.

(I might be able to play Rarity. Maybe Scootaloo or Apple Bloom, too...if that helps.)

"... You're awesome, Pinkie Pie. Thanks" Lyric said gratefully, referring to the offer to help with the invitations and her friend's understanding of her feelings for both her and Rainbow Dash. "... The invites for Dash and Flutters are at mine and Amy's house. Let's go there and pick them up, ok?"

Though Lyric was curious about when and how the cosine switch happened, the pegasus knew better than to ask. She simply giggled and walked her to where she lived with her roommate and good friend, Amoretta. "Amy, you got RD and Fluttershy's invites?"
"Yeah, right here." Amoretta said, using her magic to lift two freshly decorated, glittery and dry envelopes for her friend to put in her bag. The unicorn saw Pinkie Pie and what she was wearing and barely reacted, simply asking "Why?" as she stood there.
"It's Pinkie Pie. I stopped questioning the things she does after the first three days I had known her." said Lyricalana as the invitations were magically placed into the saddlebag she was wearing.
