I'm not quite comfortable with the thought of skipping over two entire years of character development and fleshing out relations with other people's characters. Personal opinion only.
Of course there's that. But let's not forget that time in the RP is already weird as it is. Because of how the day cycle works in SL, 1 RL day is equal to 6 day-cycles in SL.
With that in mind, we always say that time and dates are only accounted for when it's convenient, otherwise someone can sit at the bar in the 'evening' and if the RP is going in that area for a while, several days would have passed by the time they leave.
So, the concept of two years passing isn't really to represent actual time that passed that robed people of the opportunity to further develop their characters - time is passing at an accelerated rate in Lismore no matter what -, but because it's convenient to say there was time for things to be re-built.
Many times players come about saying "
I was away from SL for a while, can I say my character went off to the mountains and trained for many months to learn a new skill/look different/had a baby/-something-else-that-takes-time-to-happen-?". Some have also had pregnancies that, according to SL day cycles, would have lasted a year or more, and some have the super-fast "a few weeks" versions of that; and children in the RP grow up when it's convenient (usually when their players got tired of playing children). Thus time in the RP is a completely mad thing!
The whole "TWO YEARS HAVE PASSED!" thing is then just an official time-skip that would only really come into play if someone just so happened to ask "
how long did it take to re-build after the attack?". And if you ask "
what would everybody have done during that time?", well, everybody was re-building! There wasn't time for anything else.
...and because I have to remain politically neutral, I need to make an argument for the other option too... So let's see...
Saying simply "
a wizard did it" simplifies things so there's no need to try to understand the time skip or even speak of it.
Also puts to use the crazy magical thing floating around, says it was all spent up to power the magic that re-built the place.
It's a simple solution that doesn't require advanced explanation or understanding of SL day cycles and RP time and all that wibbly wobbly timey wimey thing, and doesn't rob anyone of potential stuff their characters would have done in 2 years time.
