Yes, friends are very important if you're starting the game together, but like I said earlier, I really don't know why a fledgling that just started a game would want to travel to another planet unless they are a Beastman aiming to become an Abomination or a Demon trying to become an Angel. The time a new Beastman, Demon, or Human spents on their own planet prepping themselves for higher-end content and travel can and should be spent learning other languages as well.
If the reason why they want to travel so early does have to do with the Beastman and Demon transformations, that would add some more gameplay and lore to the game like @islesofurth mentioned: a Demon resents the way they were born and their unholy deity as well, and they want to change their ways to help those around them rather than make them feel fear in their presence and the cold embrace of death, but to do this, they have to travel to foreign lands and learn whatever they can about these foreigners while they walk the path of benevolence.
Beastmen probably wouldn't care since they just want to know the taste of Human blood to become an Abomination, but they could learn a thing or two while slaughtering them and the Demons if they choose not to discriminate while walking this dark path.
I think the only thing I should suggest about traveling to another planet as a new player—or a player that intentionally neglected to learn other languages—is that traveling to another planet should provide more knowledge regarding the planet's language than the player's own homeworld because there is much more knowledge to be found there, but I'm not so sure if being near other players while they speak aloud via text should provide some knowledge if their language is unknown since... it could be abused.
